1. A device for transmitting a signal through a power magnetic structure having at least two apertures defining a center portion therebetween and two leg portions, comprising:
- a first input winding looped around the center portion;
a second input winding having a first portion looped around one of the leg portions in one of the right or left hand sense, and a second portion of said second input winding looped around the other leg portion in the opposite sense; and
a first output winding having a first portion looped around one of the leg portions in one of the right or left hand sense, and a second portion of said output winding looped around the other leg portion in a sense opposite to that of said first portion of said output winding.

Abstract
A method and apparatus for transmitting a signal through a power magnetic structure. A power magnetic core has one or more windings for transmitting power, and two windings for transmitting a signal or auxiliary power. The signal or auxiliary power windings are looped around features of the core so as to cancel the effect of magnetic flux circulating in the core as a result of currents flowing through the one or more power windings.

4. A method for transmitting a signal through a power magnetic structure having at least two apertures defining a center portion therebetween and two leg portions, comprising:
-
providing a first input winding looped around the center portion;
providing a second input winding having a first portion looped around one of the leg portions in one of the right or left hand sense, and a second portion of said second winding looped around the other leg portion in the opposite sense;
providing a first output winding having a first portion looped around one of the leg portions in one of the right or left hand sense, and a second portion of said first output winding looped around the other leg portion in a sense opposite to that of said first portion of said first output winding;
conducting a first input current at a first power through said first input winding; and
conducting a second input current at a second power through said second input winding and thereby inducing a first output current at substantially said second power through said first output winding. - View Dependent Claims (5, 6)
